当我单击“下一步”时，我想将电话号码从 editText 放入自定义警报对话框，如下所示：我已将 getStringExtra 放入 textView 自定义对话框，但我应该单击“是”，然后显示号码成功。但我想要的是当我单击“下一步”时，显示数字。代码 ：public void sendVerificationCode() { phoneNumber = countryCode.getFullNumberWithPlus(); // The number i want to display to custom alert dialog Intent moveVerification = new Intent(CreateUserActivity.this, VerificationCode.class); moveVerification.putExtra("sendPhoneNumber", phoneNumber); startActivity(moveVerification); finish();}public void dialogVerification() { dialogVerification = new Dialog(CreateUserActivity.this); dialogVerification.requestWindowFeature(Window.FEATURE_NO_TITLE); dialogVerification.setContentView(R.layout.custom_alert_dialog); dialogVerification.setCanceledOnTouchOutside(false); Button buttonYes = dialogVerification.findViewById(R.id.buttonYes); Button buttonEdit = dialogVerification.findViewById(R.id.buttonEdit); TextView displayNumber = dialogVerification.findViewById(R.id.displayNumber); // I want to display the number at here dialogVerification.getWindow().setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); dialogVerification.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); dialogVerification.show();}

如果您的代码位于同一活动中：
将phoneNumber作为参数传递给dialogVerification()或将其声明为全局变量以直接在任何函数中使用它。
要将其作为参数传递：
致电
dialogVerification()来自sendVerificationCode()：dialogverification(phoneNumber);
并替换这个->public void dialogVerification() {
和
public void dialogVerification(int phoneNumber) {
只需将电话号码放入 textView 中即可
displayNumber.setText(phoneNumber.toString());
将其声明为全局变量：在
onStart()类声明的正下方之前将phoneNumber声明为int phonNumber;
只需将电话号码放入 textView 中即可
displayNumber.setText(phoneNumber.toString());
否则如果这
dialogVerification是在另一个VerificationCode
将其传递给其他活动：
Intent intent = new Intent(CreateUserActivity.this, VerificationCode.class);
intent.putExtra("Phone_Number", phoneNumber);
startActivity(intent);并通过以下方式访问该号码VerificationCode：
int phoneNumber= getIntent().getIntExtra("Phone_Number");只需将电话号码放入 textView 中即可
displayNumber.setText(phoneNumber.toString());
PS：它是一个字符串，只需将 every 替换int为String, getIntExtraasgetStringExtra并删除该.toString()。

public class MainActivity extends AppCompatActivity {
EditText phonenum;
Button next;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
phonenum = findViewById(R.id.editText);
next = findViewById(R.id.button);
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
go();
}
});
}
void go(){
String somenumber = String.valueOf(phonenum.getText());
AlertDialog dialog;
final AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
alertDialog.setTitle("Number verification");
alertDialog.setMessage(somenumber + "\n" + "is your number above correct ?");
alertDialog.setCancelable(false);

我在android最新版本中使用View Binding。
我自定义了警报对话框并将所需的值传递给对话框。
private ConnectDialogBinding connectDialogBinding;
private String chargerID;
private void connectDialog() {
// Create the object of
// AlertDialog Builder class
AlertDialog.Builder builder = new AlertDialog.Builder(ConnectActivity.this);
connectDialogBinding = ConnectDialogBinding.inflate(getLayoutInflater());
builder.setView(connectDialogBinding.getRoot());
connectDialogBinding.txtID.setText(chargerID);
builder.setCancelable(false);
// Create the Alert dialog
AlertDialog alertDialog = builder.create();
// Show the Alert Dialog box
alertDialog.show();
connectDialogBinding.cancelBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
alertDialog.cancel();
}
});
}

您可以创建一个静态类并创建一个静态字段来保存phoneNumber变量值。然后您可以在任何地方访问您的phoneNumber 变量。不是最佳实践，但这种方法总能奏效
